AXLE-SKEIN AND SAN D-COLLAR.

Specification of Letters Patent.

Patented May 29, 1906.

Application filed March 8, 1904. Serial No. 197,183.

T0 @ZZ whom it may concern:

Be it known that I, THOMAS R. MCKNIGHT, residing at Aurora, in the county of Kane and Stateof Illinois, have invented certain new and useful Improvements in VAxle- Skeins and Sand-Collars, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to axle-skeins, and has for its object to provide a new and improved axle-skein which will be capable of being applied to ordinary metal wheel-spindles after they are worn out, thereby providing a new spindle which serves the same purpose as the old one.

A further object protection for the is to provide adequate bearing-surface of the skein against sand and dirt, thereby making the axle especially well adapted for usel on wheeled Scrapers and other implements used in similar work and in other situations where there is great exposure to sand and dirt.

I accomplish these objects as hereinafter described and as illustrated in the drawings.

What I regard as new is set forth in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view. Fig. 2 is asection on line 2 2 of Fig. 1. Fig. 3 is a partial section on line 3 3 of Fig. 1. Fig. 4 is a partial section on line 4 4 of Fig. 1. Fig. 5 is a partial side view of the pipe-box; and Fig. illustrating the collars at the inner end thereof.

Referring to the drawings, 10 indicates an ordinary axle-spindle which projects from a squared axle 1 1 and is provided with a threaded end 12 to receive a nut 13 in the usual way.

14 indicates a skein which is adapted to fit upon the spindle 1() and is provided at its inner end with a squared portion 15, adapted to receive the squared portion 11 of the axle and to fit tightly thereupon. The skein 14 is somewhat longer than the spindle 10, so that its outer end may be brought flush with the outer end of said spindle, as shown in Fig.

. 1. It will be understood that the inner surface of the skein 14 is shaped to fit the spindle 10, so that it is supported thereby. The outer surface of the skein 14 is suitably shaped to serve as a spindle for a pipe-box or sleeve 16, which is adapted to be fitted in the hub 17 of a wheel, as shown in Fig. 1.

The nut 13 is provided with a flange 18, which is somewhat greater in diameter than the internal diameter of the pipe-box 16, so that the nut 13 when in place on the screwthreaded portion 12 of the spindle 10 serves to hold all the parts together.

The pipe-box 16 is provided on its outer surface with a number of ribs 19, as best shown in Figs. 4 and 5, said ribs serving toA secure the pipe-box in rotation in the hub. The inner ends of the ribs 19 terminate a short distance from the inner end of the pipe-box 16, thereby provid-l place and prevent itsing a projecting portion 20, as shown infF-igs.y v

1 and 5. pipe-box is adapted to fit into an annular recess formed by providing the an intermediate collar 21 as Fig. 1. The outer portion tends forward substantially best shown in or recess is provided around the skein near its skein 14 with.

of said collar ex-v parallel with the outer surface of the skein 14 and a short dis-j tance therefrom, so that an annular channel The projecting portion 20 of the inner end which receives the projecting portion 2() of the pipe-box which fitstherein and also has an end bearing therein, as shown in Fig. 1. The collar 21 thus forms an end bearing for the inner end of the pipe-box, which is protected from dust and dirt by the overhanging portion of such collar. Furthermore, as shown in Fig. 1, the hub 17 is arranged to extend over or inclose the collar 21 so that double protection is secured against admission of dirt to the bearing-surfaces.

As best shown in Fig. 1, between the collar 21 and its inner end the skein 14 carries a dished collar 22, the outer surface of which is convex, its inner surface being concave, as shown in Fig. 1. The collar 22 is set a short distance from the collar 21, forming a space or pocket 23 between said. parts. Furthermore, the collar 22 is of somewhat greater diameter than the collar 21. That surface of the collar 21 which lies next to the collar 22 is beveled, as shown in Fig. 1,.being approximately parallel with the inner surface ofthe collar 22, as shown. The pocket 23, thereof the spindle.

fore, is angularly disposed, its outer portion lying deeper in the hub than its inner portion. The hub is recessed to receive the collar 22, the latter being provided With angular lugs 24 at suitable points in its periphery, Which serve as scrapers to clear out the dirt accumulating in the recess in the hub, and thereb'y prevent, to a considerable extent, such material from Working in between said collar and the hub. As shown in Fig.l 2, the margins of the lugs 24 are inclined, so that they better serve to remove the dirt from the hub. By the construction described I provide an effectual seal against the admission of sand and dirt to the bearing-surface of the skein 14, since in order to gain access thereto the dirt must notonly pass the pocket 23, but must also Work down between the collar 2l and pi e-boxl 16, passing around the proj ecting en of said pipe-box.

I Wish it to be understood that, broadly considered, my invention is not restricted to the use of both collars, although such construction constitutes a further improvement, Which is particularly covered in subsidiary claims.

By my invention I provide means Whereb old Worn-out axles mayreadily be renovate and, further,l I secure effectual protection against the admission of sand and other gritty-matter between the bearing-surfaces moreover, that although my improved skein is designed vparticularly for application to Worn-out orotherWise-disabled spindles, it may also be applied to spindles in good con* dition, thereby securing the benefits of the protective features above described. I Wish it to be understood, further, that except in so far as they are particularly claimed my invention is not restricted to the details of the construction described, but includes, generically, the subject-matter of the broader claims.
